Hey guys, I have a smith & Wesson 0410. I am thinking about picking up a PX4 in .40 at the next 1500, and would like to put the S&W towards some of the price, but i do not know how much I could pull out of it. It's in mint condition w/ box, instructions, and 2 magazines. Has probably had 500 rounds through it, but is cleaned after every time to the range. I've seen $470 new, but I have no idea what using guns does to the value. Any help would be appreciated. Only have two weeks till the 1500!
